3D printing biodiversity back into cities

Could we create greener cities with these printed 'reefs'?

Spotted: Most of us live in cities, where biodiversity is often in short supply. Not only can this lead to a feeling of disconnect from the natural world, but it also contributes to growing pollution levels and climate change. Urban Reef is hoping to change this by transforming urban areas into vibrant ecosystems.

Urban Reef uses 3D printing technology to create open-ended habitats that encourage the growth and diversity of life in urban settings. ‘Reefs’ are created using bio-based algorithms and are 3D printed using printers designed to work with fluid-dense materials like ceramics and clay. Because they are porous, the printed ‘reefs’ retain water and provide refuge for many urban species, increasing biodiversity.

Unlike conventional green spaces, such as parks, Urban Reef’s designs form dynamic, living ecosystems that actively contribute to urban sustainability. The living structures filter air, support biodiversity, absorb rainwater, regulate humidity, and cool local microclimates, all of which improve the urban environment.

Urban Reef’s co-founder Pierre Oskam told Springwise that, “Modern urban development often overlooks the natural dynamics of ecosystems, leading to cities that exclude or disrupt nature.” To counter this, Urban Reef creates structures that are “a step towards “rewilding” cities (…)  addressing both pragmatic and cultural challenges in urban planning.”

Urban Reef collaborates with urban planners, architects, communities, and local governments to integrate its solutions into broader urban development strategies and help urban residents understand the benefits of green infrastructure. At the same time, the company is exploring new applications for its living structures, such as improving stormwater management and enhancing carbon sequestration. Funding for Urban Reef’s projects is provided by municipalities and grants.
